alt=\"\"/></p><p>　　不管是共享单车、扫码支付，还是健康宝、寄快递，王宝义的操作都很娴熟，但起初他并不接受这样的生活方式，甚至有些抵触。</p><p>　　河北唐山迁安市燕阳小区居民王宝义说：&ldquo;原来孩子说给我买智能手机，我很抵触，说实话我对新鲜事物真的特别抵触，我说什么样的手机不都是打个电话吗？&rdquo;</p><p>　　然而，因为一次买火车票的经历，让王宝义改变了他最初的想法。</p><p>　　王宝义说：&ldquo;本来我想起早，提前（到火车站）把车票买好，结果孩子就说从手机上给你买，当时我都不相信，但是第二天上车，我把身份证一撂，火车票就发给我了。出于好奇心我就接触了智能手机，我就学会了缴水费、缴电费、扫码支付、购物，不学不知道，只要一学真是离不开（手机）了，非常方便。&rdquo;</p><p>　　实际上，像王宝义这样主动学习并且能够熟练使用智能手机的老人并不多。根据中国互联网信息中心2022年2月发布的第49次《中国互联网发展状况统计报告》显示，截至2021年年底，我国网民规模达10.32亿。网民中，60岁以上的老年人只占11.3%。而在这些老年人中只有30%能独立完成出示健康码、行程卡的活动，23%能在网上购买生活用品，20%能在网上查找信息。也就是说5位老年人当中，只有一位能够相对熟练地使用手机完成上述操作。</p><p style=\"text-align: center;\" class=\"photo_img_20190808\"><img src=\"//p2.img.cctvpic.com/photoworkspace/contentimg/2022/03/27/2022032721461637518.jpg\" alt=\"\"/></p><p>　　想用不会用，会用不敢用，这是大多数老年人在使用智能手机时面临的问题。</p><p>　　中国信息通信研究院副院长胡坚波说：&ldquo;到应用商店下个东西，要去点击什么东西，他（老年人）都不太懂。另外，一般老年人询问自己子女怎么用，大概只有30%左右才能真正得到有效答复，根据我们调查有60%的老年人不敢使用电子支付，担心一扫码钱就没有了，或者担心账号密码被窃走了。而且80%以上的老年人都曾经遭遇过使用互联网应用的时候有弹窗，弹窗以后不知道怎么弄，所以感觉非常不好。&rdquo;</p><p>　　正是因为这些应用中操作比较繁杂，面对这样的新生事物，很多老年人不想学，更不愿用。</p><p>　　中国人民大学人口与发展研究中心副主任宋健说：&ldquo;我觉得是意愿上，老年人可能相对会有一点传统的观念，觉得玩手机、玩电脑，不太清楚手机和电脑里那个世界对他意味着什么，所以在意愿上更愿意遵循传统的生活，就不太愿意接触或者开启新的生活。&rdquo;</p><p>　　数字时代，如何让老年人充分享受智能化服务带来的便利，让老年人更好共享信息化发展成果？2020年11月24日，国务院办公厅印发了《关于切实解决老年人运用智能技术困难的实施方案》，聚焦老年人日常生活涉及的出行、就医、消费、文娱、办事等7类高频事项和服务场景，回应了许多社会关切。工业和信息化部也推出《互联网应用适老化及无障碍改造专项行动方案》等举措，加快推进互联网应用适老化改造的进程。</p><p style=\"text-align: center;\" class=\"photo_img_20190808\"><img src=\"//p2.img.cctvpic.com/photoworkspace/contentimg/2022/03/27/2022032721474127687.jpg\" alt=\"\"/></p><p>　　中国信息通信研究院副院长胡坚波说：&ldquo;我们也是推动了首批互联网网站和APP的改造，我们一共实施了325项改造，其中50项是与老年人相关的APP，经过适老化改造的这些网站或者是APP主要有这么几个特点，一个是大的字体、大的图标、高对比度，操作非常简单，特别重要的是没有中间插件，没有弹窗，这对老年人都非常重要。&rdquo;</p><p>　　记者也专门走访了几家老年人使用率比较高的例如微信、银行、电信等相关企业，看看他们在适老化改造上都做了哪些改变。</p><p>　　腾讯公司公共事务部总经理杨翔宇说：&ldquo;点击微信，在右下角的&lsquo;我&rsquo;，&lsquo;设置&rsquo;，有关怀模式，同时开启听文字消息，老年用户在使用这项功能的时候避免了有的时候文字比较多，或者说有些字不认识，他只要轻轻一点击，就可以把文字消息以语音播报的形式清晰地朗读出来。&rdquo;</p><p>　　从对比中我们可以看到，微信的关怀模式中，字体明显变大，同时新增设的语音播报功能也解决了视力障碍或认读困难的老人的阅读问题。老年人经常去银行办理业务，针对老年人的特点和使用习惯，手机银行APP都做了哪些适老化改造呢？</p><p>　　中国工商银行网络金融部总经理梅超说：&ldquo;客户下载或者登录手机银行APP，系统会自动提醒是不是要切换到老人版的专属版本。通过提供大字版、语音读屏、增加辨识度来解决阅读障碍和操作障碍。&rdquo;</p><p style=\"text-align: center;\" class=\"photo_img_20190808\"><img src=\"//p3.img.cctvpic.com/photoworkspace/contentimg/2022/03/27/2022032721502481138.jpg\" alt=\"\"/></p><p>　　在办理电信业务的时候，很多老年人会拨打客服电话，但是适老化改造前，复杂的步骤常常让他们不知所措。适老化改造后，手机号码经过实名认证、65岁以上的老年人在拨打客服电话时，系统自动识别，一键呼叫人工客服，无须再经过语音提示、数字选择等环节。</p><p>　　中国电信北京公司洋桥营业厅厅经理黄蕊说：&ldquo;客服会有尊长专席直接接通，不用等待，所有的问题都会有专人答复，比以前方便多了。&rdquo;</p><p>　　大字体、大图标、大音量、一键呼叫人工客服以及简洁易操作的页面，很多企业APP的适老化改造都推出了助老模式。改造效果怎么样？老年人使用体验是否得到了改善？我们听听老年用户怎么说。看来线上的适老化改造确实让老年人使用起来更加简单便利，然而针对一些学习困难，或者不具备条件的老年人，在线下也应该为他们留一扇温暖的窗口。</p><p>　　中国人民大学人口与发展研究中心副主任宋健说：&ldquo;老年人习以为常的生活通道，不要统统关掉，要给他们留一扇窗，给他们留一条道，给他们提供更人性化服务。&rdquo;</p><p>　　在服务意识上做&ldquo;加法&rdquo;、在应用操作上做&ldquo;减法&rdquo;，只有弥合老年人与数字社会的隔膜，解决两者的&ldquo;适配&rdquo;问题，才能让更多的老年人更好地融入数字时代。近日，国务院印发《&ldquo;十四五&rdquo;国家老龄事业发展和养老服务体系规划的通知》，通知要求完善传统服务保障措施。对医疗、社保、民政、金融、电信、邮政、出入境、生活缴费等高频服务事项，设置必要的线下办事渠道并向基层延伸。公共服务场所应保留人工窗口和电话专线，为老年人保留一定数量的线下名额。</p><p style=\"text-align: center;\" class=\"photo_img_20190808\"><img src=\"//p2.img.cctvpic.com/photoworkspace/contentimg/2022/03/27/2022032721524976801.jpg\" alt=\"\"/></p><p>　　在福建省莆田市第一医院，门诊大厅在&ldquo;有健康码进入通道&rdquo;的旁边，专门设置了&ldquo;无健康码无手机填单处&rdquo;，安排了专人指导填写个人身份信息和近期健康情况及健康承诺书，换取纸质版健康码通行证就医。</p><p>　　在无锡火车站每天3班人员轮流值守，为使用老人机、没有微信、没有手机以及无法出示健康码的旅客提供专门服务。</p><p>　　在山东，济南国际机场信息技术管理部与济南市卫建委、市大数据局对接，自主研发了健康码核验系统软件，方便老年人出行。</p><p>　　《&ldquo;十四五&rdquo;国家老龄事业发展和养老服务体系规划的通知》还强调，要加强身份证信息归集和数据互联互通，在更多领域推广&ldquo;一证通行&rdquo;。并定期开展拒收现金专项治理。同时，优化线上线下政务服务，让老年人办事少跑腿。</p><p>　　在国家层面，国务院办公厅印发的这份实施方案，不仅把老年人在数字时代里的每一点不方便，都看作一件必须解决好的大事，也把部分地方已经先行一步对老年人的关照方式上升为全国通行的要求，也更系统地提出了解决老年人运用智能技术困难的一揽子方案。</p><p>　　与此同时，我们也看到社区、老年大学以及爱心企业等等也努力为愿意主动学习的老年人提供培训，帮助他们适应这个数字化的时代。</p><p style=\"text-align: center;\" class=\"photo_img_20190808\"><img src=\"//p3.img.cctvpic.com/photoworkspace/contentimg/2022/03/27/2022032721590468348.jpg\" alt=\"\"/></p><p>　　王宝义所在社区的&ldquo;智能手机学堂&rdquo;又开课了，志愿者为老人详细讲解如何使用微信小程序、出示健康码、线上预约挂号、视频聊天与扫码支付等功能。</p><p>　　如何让智能技术发展适应老龄化社会步伐，填平&ldquo;数字鸿沟&rdquo;，是经济社会持续健康高质量发展所面临的&ldquo;必答题&rdquo;。特别是数字化应用将会更广泛更深入，所以这样的智慧助老行动还要持续推进。同时，还应该双管齐下，坚持传统服务与智能创新相结合、线上服务与线下渠道相结合。政府、社会、企业、家庭等各个方面共同努力，不断提供更多更周全更贴心的适老化服务，老年人才会在数字社会里有更多获得感、幸福感、安全感。</p><!--repaste.body.end-->\n"

text-align: left;\">我们已经知道，宇宙中的一切事物都处在永恒的运动变化之中，静止只是暂时的、相对的。北斗星的七颗星也是在各自运动着。这1颗星中有2颗是3等星，4颗是5等星。用直线把勺形边上的两颗星连起来，并向斗口方向延长约6倍远，就找到了北极星。这样北斗星成了寻找北极星的有利工具。然而天文学家们指出，随着时间的推移，它将失去这个用途，并且它自己的样子也将发生改变。</p><p style=\"text-indent: 2em; text-align: left;\">这七颗星运行的速度和方向各不相同，摇光和天枢朝一个方向，其他6颗朝同一个方向。这样可以算出它们在47万年前和47万年后所组成的图形，那是和今天的样子有很大差别的。</p><p style=\"text-indent: 2em; text-align: left;\"><strong style=\"color:#125b86\">十万个为什么2</strong></p><p style=\"text-indent: 2em; text-align: left;\">什么是暗物质</p><p style=\"text-indent: 2em; text-align: left;\">暗物质也叫不可视物质，这类物质是否真实存在于广阔无垠的宇宙中，至今科学还不能做出最后的定论。然而很多证据表明了它存在的可能性。</p><p style=\"text-indent: 2em; text-align: left;\">天体物理学的一个最新研究成果表明，各种化学元素的总和，按质量不超过宇宙总质量的113，其余713的质量由暗物质提供的。也就是说，人类现今所认识到的物质，并不是宇宙间的主要成分，而只占其质量的113。这一成果引出了人们对暗物质的各种推测。</p><p style=\"text-indent: 2em; text-align: left;\">暗物质的概念最先由瑞士天文学家兹威基提出。他在用光度方法和动力学方法估计后发星系团的质量时，发现后者测得的质量为前者的122倍。这表明后发星系团的主要质量并非由可视的星系贡献的，这种还未被发现和证实的物质就被称为“下落不明的质量”，即暗物质。</p><p style=\"text-indent: 2em; text-align: left;\">一直以来人们对暗物质有很多种猜测，例如认为它是气态物质，尘埃、变暗的星等等，然而这些猜测后来都被科学否定了。目前，对暗物质的研究已经有了新的进展，认为它是由中微子大量聚积而产生的。</p><p style=\"text-indent: 2em; text-align: left;\">相信，随着科学研究的深入，暗物质的问题会逐渐明朗起来。</p><p style=\"text-indent: 2em; text-align: left;\"><strong style=\"color:#125b86\">十万个为什么3</strong></p><p style=\"text-indent: 2em; text-align: left;\">什么是黑洞</p><p style=\"text-indent: 2em; text-align: left;\">“黑洞”是一类质量特别大的超巨星坍缩形成的。恒星中心的铁核在自身重量的作用下迅速地收缩，发生强力爆炸。由于恒星的核心质量大到使坍缩过程无限地进行下去，形成一个密度高到难以想象并且还在增高的物质团。这个物质团由于质量之大、密度之高，而具有了强大的引力场，它是不能被“看见”的。这种引力大到它周围的任何东西，甚至光，都被吸到其中去，就像是宇宙中神秘而危险的洞穴，因而被称为黑洞。</p><p style=\"text-indent: 2em; text-align: left;\">这一概念最先提出是在3456年，普林斯顿大学的物理学家惠勒(7738+3,,-,.)的一篇题为《我们的宇宙，已知的和未知的》的文章中。</p><p style=\"text-indent: 2em; text-align: left;\">现在，“黑洞”作为一个假想的天文名称为人们所熟悉。已经有越来越多的证据来证明它的真实存在。因为黑洞无法被看见，所以这些证据只能间接通过物质落进“黑洞”所发出的辐射得知。</p><p style=\"text-indent: 2em; text-align: left;\"><strong style=\"color:#125b86\">十万个为什么4</strong></p><p style=\"text-indent: 2em; text-align: left;\">什么是银心</p><p style=\"text-indent: 2em; text-align: left;\">近年美国的太空望远镜发现银河星带内的人马座方向有大量射线射出。这种观测表明，人马座中有一个强射电源，该射电源内部有一个直径达1光年以上的中央核，这个核在天文学上被称为银心。银河系银盘上所有恒星(包括太阳)都绕着它旋转，如同地球绕着太阳旋转一样。在某种意义上来说，与太阳在太阳系中的地位一样，银心是银河系的主宰，是太阳的“太阳”。</p><p style=\"text-indent: 2em; text-align: left;\">为什么银心会成为银河系的主宰呢?这首先是因为它具有极大的质量。太阳距银心约2233光年，绕银心公转的平均速度是453公里/秒，根据牛顿677·34/8的离心力定律，可间接得到银心质量的数据约为1+,-1311-7太阳质量，整个银河系.3/以上的质量都聚集在银心中。</p><p style=\"text-indent: 2em; text-align: left;\">银心质量很大，又有强烈的射电辐射，它比太阳更炽热更明亮。但是我们却看不到它。银河系赤道平面外围有一圈由较冷物质构成的星系盘，有2万光年之厚，而地球正在银盘内部，所以在距离银心非常之远的地球上，隔着如此之厚的银环尘埃，当然不可能看到银心的光亮了。</p><p style=\"text-indent: 2em; text-align: left;\"><strong style=\"color:#125b86\">十万个为什么5</strong></p><p style=\"text-indent: 2em; text-align: left;\">为什么星星会眨眼睛</p><p style=\"text-indent: 2em; text-align: left;\">小朋友抬头望夜空，星星都在对我们眨眼睛，这是怎么回事?难道星星真的有眼睛?不是的，星星根本没有眼睛，因此也不会眨眼睛。</p><p style=\"text-indent: 2em; text-align: left;\">我们知道，我们居住的地球外面包着一层厚厚的大气层，里面有热气也有冷气，热气不断地上升，冷气不断地下降，风吹来吹去，使大气不停地在翻腾，我们看星星须透过这厚厚的大气层，大气层挡在我们面前遮住了星星，由于大气层不停的在晃动，从远处看星星，好像星星在闪动，在对我们眨眼睛，其实不是星星动，而是大气层在不停地动。</p><p style=\"text-indent: 2em; text-align: left;\"><strong style=\"color:#125b86\">十万个为什么6</strong></p><p style=\"text-indent: 2em; text-align: left;\">什么是矮星</p><p style=\"text-indent: 2em; text-align: left;\">矮星是恒星演化成的，是一种特殊的恒星。它们的光度和体积都很小，是恒星中的矮小者。按其表面温度高低分为白矮星、红矮星、黑矮星，还有近年新发现的褐矮星。</p><p style=\"text-indent: 2em; text-align: left;\">恒星“老年”的时候，它内部的一系列核反应停止或接近尾声之时，它外层的物质挡不住中心的引力而发生收缩，在收缩过程中释放出的能量使其表面温度达到133336以上，成为白矮星，发出耀眼的白光;后来白矮星温度逐渐降低，就变成了红矮星;而褐矮星则是老年的红矮星，它的温度比红矮星低，其内部的热核燃料已快消耗完了;当褐矮星的温度进一步降低，最后完全冷却，不再具有发光能力，于是就变成一颗死寂的黑矮星了。</p><p style=\"text-indent: 2em;

text-align: left;\">雨的时候青蛙为什么会叫</p><p style=\"text-indent: 2em; text-align: left;\">每到下雨天，青蛙就会叫得特别响。尤其是在快要下雨的时候，青蛙的叫声此起彼落，一阵比一阵大声，真好像在开演唱会。</p><p style=\"text-indent: 2em; text-align: left;\">青蛙不喜欢在太冷、太热或太干燥的环境里生活，它们喜欢阴凉潮湿的地方，所以下雨的时候，对青蛙来说，真是兴不过了。尤其在经过一段天晴燥的日子，天快下雨的时候，因为气压下降，湿度增加，空气中的水分加多，青蛙的皮肤得到充分湿润，于是就活跃起来了。</p><p style=\"text-indent: 2em; text-align: left;\">同时，在阴雨连绵的季节里，很多昆虫都在这时候大量繁殖，这些昆虫就是青蛙的食料。而这时候青蛙也刚度过寒冷干燥的冬天，正需要大量捕食昆虫，以恢复体力。在又有好食物、又有好环境的情况下，青蛙就不禁纷纷高声歌唱;借此机会，雄、雌蛙也在池畔水边交配繁殖后代。</p><p style=\"text-indent: 2em; text-align: left;\">夏天的夜晚，酷热难当。田野里传来一阵阵青蛙的叫声：“呱——呱——呱”、“呱——呱——呱”，这种动物大合唱常常会此起彼伏，整夜地回荡在夜空中。</p><p style=\"text-indent: 2em; text-align: left;\">青蛙是一种两栖动物，就是说，它们既能在水里生活，也能在陆地上栖息。不过，还没有变成青蛙的小蝌蝌却离不开水，因为它们是用像鱼一样的鳃来呼吸的。小蝌蚪长成青蛙以后，慢慢地习惯用肺来呼吸了，这样，它们就能在陆地上生活了。</p><p style=\"text-indent: 2em; text-align: left;\">尽管青蛙是水陆两栖的动物，但是它们好像更喜欢水中的生活。我们经常可以看见，水边的青蛙一会儿“扑通、扑通”跳进水里，一会儿又跳上岸边或者荷叶上。至少，青蛙们都很喜欢潮湿的环境。所以，每当要下雨之前，空气里湿度变得越来越高，这时候，田野里的青蛙们，便会“高兴地”叫个不停。当大雨落下时，池塘里的青蛙，更是欢快地蹿上跳下，忙个不停。</p><p style=\"text-indent: 2em; text-align: left;\"><strong style=\"color:#125b86\">十万个为什么9</strong></p><p style=\"text-indent: 2em; text-align: left;\">昆虫为什么要脱皮</p><p style=\"text-indent: 2em; text-align: left;\">昆虫的蜕皮是生长的需要，因为昆虫的表皮(外骨骼)是由蜡质层和几丁质层组成的。蜡质层位于表层的最外层，可以防止水分的蒸发。</p><p style=\"text-indent: 2em; text-align: left;\">几丁质是复杂的含氮多糖类，它是外骨骼的主要成分。在几丁质层的下面是分泌外骨骼的表皮细胞。表皮细胞分泌的外骨骼一经硬化后，就不能继续扩大，从而使昆虫生长受到限制。因此昆虫在生长发育过程中会出现蜕皮现象。蜕皮时，表皮细胞分泌一种酶，将几丁质溶解，同时蜡质层破裂，昆虫的幼体就可以从外骨骼中钻出来，并且由表皮细胞重新分泌外骨骼。当新的外骨骼还未完全硬化之前，昆虫身体可以增大。外骨骼的硬化是因为蛋白质的变性的原因。所以，正在发育而迅速生长的昆虫幼体蜕皮次数较多。当昆虫发育到不再继续长大时，蜕皮也就停止。完全变态的昆虫最后一次蜕皮以后，蜕皮激素分泌正常，保幼激素分泌减少，进入蛹期。</p><p style=\"text-indent: 2em; text-align: left;\">一只昆虫从卵孵化成为幼虫，幼虫期要脱几次皮，每脱一次皮就增加一龄，就像高等动物长大一岁一样。刚从卵里孵出来的小虫叫第一龄，脱过第一次皮叫第二龄，脱过第二次皮叫第三龄，照此推下去，把幼虫脱皮的次数加上一就是幼虫的龄期。</p><p style=\"text-indent: 2em; text-align: left;\">昆虫为什么要脱皮呢?因为昆虫不具有高等动物的骨骼系统，靠身体外的体壳起皮肤和骨骼的作用。这种体壳也称为外骨骼或体壁。体壁虽然保证了昆虫更有利地适应各种自然环境，但它在昆虫身体各部分的薄厚不一样，有些厚的和硬的地方发生了骨化，缺乏弹性，当幼虫长到一定阶段，虫体的生长受到限制，它就要脱掉旧皮，换上新皮才能继续生长。</p><p style=\"text-indent: 2em; text-align: left;\">昆虫脱皮是其生命中不可少的环节。昆虫幼虫每脱皮一次，不仅使它们的躯体增大，内部各器官得到进一步的发展，同时，外部形态也发生了变化。另外，由于昆虫的皮是由新陈代谢的产物形成的，所以脱皮也有排泄的作用。昆虫幼虫的生长和形态变化，由于脱皮而显出一定的规律性，例如为害蔬菜的粉蝶就脱皮!次。</p><p style=\"text-indent: 2em; text-align: left;\">昆虫更换外衣的过程，是受到身体中内分泌器官的控制。当昆虫长到一定的时候，它就分泌出一种皮激素，把昆虫旧表皮和真皮细胞分离，渐渐形成了薄薄的新表皮，最后，昆虫收缩腹部肌肉来增加胸部的血压，使背部向上拱起，于是，旧表皮沿着胸部背面特别脆弱的地方脱出。例如蝉在脱皮时，从背部中央“&quot;”形地方裂开，从外表皮里蠕动，先头后尾，慢慢地爬出来。生活在水中的昆虫，借助它们吸收了空气或水后，使身体膨胀，也是在旧表皮的特别脆弱的地方裂开，以后靠蠕动的力量脱出柔软的昆虫体。</p><p style=\"text-indent: 2em; text-align: left;\"><strong style=\"color:#125b86\">十万个为什么10</strong></p><p style=\"text-indent: 2em; text-align: left;\">蝴蝶为什么是益虫</p><p style=\"text-indent: 2em; text-align: left;\">所谓害虫和益虫是对于人来讲的，对人的生产生活有危害的就成为害虫，有益的就是益虫，其他的则归为中性昆虫。蝴蝶的幼虫肯定是鳞翅目昆虫，如果它们在田里或者绿化带或者苗圃中，对我们的生产生活造成危害了，肯定归为害虫了。但如果在其他地方，没有影响到我们的生活，只能称为中性昆虫。而成为成虫后，一部分蝴蝶就不再取食，直到交配后死亡，这也称为中性昆虫，另一部分靠取食花蜜，就是益虫了。</p><p style=\"text-indent: 2em; text-align: left;\">其实蝴蝶给人类造成物质损害的种类并不多，如危害水稻的稻弄蝶、稻眉眼蝶，危害十字花科蔬菜(卷心菜)的菜粉蝶，危害柑橘的玉带凤蝶和柑橘凤蝶，加害樟树的樟凤蝶，加害铁刀木的迁粉蝶。绝大多数蝴蝶成虫都是有益的，如为植物传播花粉，维持生态平衡，美化了大自然。此外还有专吃蚜虫的蚜灰蝶，还有其他可供药用或食用的种类。</p><p style=\"text-indent: 2em; text-align: left;\">蝴蝶有很少类在成虫后会继续危害植物，如果影响到人的生产生活，它们就仍是害虫。答案补充就算伤害植物，也不能算是害虫，人类对害虫与益虫的区别就是是否危害到人类的生产生活。如果数量在一定基数下，且危害的植物跟人类生活不紧密，也只能算中性昆虫。举个例子，蝗虫与蚱蜢这两个东西有区别么?当其聚集在一起时，称蝗虫，危害大。而人工养殖，用来做饲料和食物的时候就是益虫了。没有绝对的益虫，也没有绝对的害虫。蝴蝶同样是这样的。人类是唯我的，对人类有益就益虫，有危害就害虫，所以要具体分，还是要在特定的环境下，才能定义。</p><p style=\"text-indent: 2em;
